IMPORTANT INSTRUCTIONS
WARNING: Risk of scalding or other severe injury.
• Before completing installation, the installer must set the maximum water
temperature setting of this valve to minimize the risks associated with scalding
hazards according to ASTM F 444.
• Do not install a shut-off device on either outlet of this valve. The installation of
any such device may create a cross-flow condition at the valve and affect the
water temperature.
• Factors that change the temperature of the water supplied to the valve, such as
seasonal water temperature changes, and water heater replacement or servicing,
will change the maximum water temperature supplied by the valve and may
create a scalding hazard. The pressure-balanced valve will not compensate for
changes in the water supply temperature; adjust the maximum water temperature
setting of this pressure-balanced valve when such changes occur.
• Pressure-balanced valves may not provide protection against scalding if there is a
failure of other temperature-limiting devices elsewhere in the plumbing system.
NOTICE: Only apply silicone based lubricants to these valves. Do not use petroleum
based lubricants. Petroleum based lubricants will harm the O-rings, seals, and plastic
components.
The installer is responsible for installing the valve and adjusting the maximum water
temperature of this pressure-balanced valve according to instructions.
This valve meets or exceeds ANSI A112.18.1 and ASSE 1016.
